Sitewide header location

I've searched thru many threads and can't seem to find the answer to how to position the sitewide header navigation area in the center of the page. Seems like the sitewide header site title area (which is empty) is pushing the nav area to the right. I'm new to concrete5 and liking the functionality. Apologies if this is a noob question but couldn't locate a explanation I could use. Thanks in advance.
